¶ Garbo
Garbo is a goblin who resides in the far upper-left corner of the Goblin's Retreat. His primary purpose is to recycle old or deprecated items in exchange for Coins or other resources. Garbo does not accept any deliveries or flowers and will not give any rewards for them.
After a Chapter has ended, you can exchange the unused Tickets for Coins. The exchange rate is extremely low, so don't plan on making any money this way.
The Dung and Weeds that you collect from your friend's farms when helping out can be sold for Coins, though it is arguably better to give them to Goblet instead.
If you are a new player, it is unlikely that you will need to visit Garbo for any reason.
Garbo used to take Earthworms and Grubs, which was useful when you had a large amount of them from repeated composter use, but as of Chapter 11 he does not.
